Sleep

From being a pretty good sleeper (in the parent definition) Isolde has started waking up several times a night. Since she was two and a half months old (she's now four and a half) she's been sleeping at least five hours straight and on average six-seven hours (sometimes eight-nine hours but that's pretty rare). On a typical night she'd fall asleep at nine or ten o'clock and sleep until four or five in the morning. But for the past week she has gone to bed at nine or ten as usual but then woken up around midnight and then every hour or every other hour for the rest of the night (last night she slept six consecutive hours but that's because she fell asleep at 18:15; she still woke at midnight). A few nights she's been wide awake for two hours in the middle of the night. For the first couple of months of her life it was easy to make her fall asleep again at 6 or 7AM but now she's awake and want to play. That's fine though. We often get up, play for a while, eat breakfast, and then we go back to bed between let's say 8 and 9 or 10 am. Normally that's not a problem (I get enough sleep) but now, with me getting such interrupted sleep (and sometimes being awake for two hours), we have slept even longer in the morning. At the same time or as a result, she's taken longer naps during the day, and now I fear that her daily rhythm is off. I don't know whether to wake her though. Feels like she's still too young for me to try to steer her sleeping except for the evening bedtime but maybe it's time?

I asked our nurse B if the move has upset Isolde but she didn't think so. She said babies are not that sensitive to their environment, not as long as they are still with people (and stuff) they recognise. Isolde did sleep fine for the first three or four days in the new flat though, but maybe it took her a few days to notice new sounds and smells? B thought instead that I'd been stressed (over the move) and had less milk as a result (I have noticed that myself actually but I thought it was my breasts finally being balanced so-to-speak) and that Isolde wakes up at night simply because she's hungry. She ordered me to drink more water (which I have been forgetting lately) and also try to feed her more in the evening. I have followed her advice and my breasts have now re-filled but Isolde is still not sleeping properly... We have started giving her porridge, which I hope will fill her up in the evening... as soon as she gets that she supposed to swallow (so far she's been eating 5 ml/ a table spoon at the most).

My other theory is that she's disturbed by us. We have gone to bed at 11 pm or midnight and soon (up to an hour) after that she wakes up. She's not that sensitive to noise otherwise in the evening (the hoover going or cardboard boxes being dismantled) and we don't turn on lights or make much noise when we go to bed, and it was never a problem at the old flat, but maybe she's disturbed by us turning in bed, snoring (?) or whispering? We still don't have a bed and no blinds in our bedroom so we're sleeping in Isolde's room. Maybe letting her sleep alone would make her sleep better?

All you mothers out there, any advice?! I want this sleeping beauty back!
